Next-Gen Aerial Retardant
FORTRESS FR-300 is our aerial dry powder long-term retardant purpose-built for fixed tank helicopters. FORTRESS FR-300 has a medium viscosity rating and high-visibility (HV) fluorescent coloring. FORTRESS FR-300 features our unique magnesium chloride formulation, which means that it's more effective, safer for the environment, and more durable than conventional, fertilizer-based retardants. This product is currently in development.

Designed for dry bulk storage and dry base operations.
Engineered for stronger fire barriers and superior fire control. Purpose-built for fixed tank helicopters.
Gum-thickened medium viscosity for improved drop characteristics.
Provides higher visibility during the day and at night, and fades over time when exposed to sunlight.
Self-hydrating when humidity exceeds 35%, enabling better fuel coverage, more effective fire suppression, and extended durability.
Not a fertilizer, does not contribute to the growth of flammable vegetation or freshwater eutrophication, does not contain any biocides, and is significantly less toxic to fish.
Corrosion inhibitor package minimizes corrosion on steel, brass and aluminum, making it safe for use around steel utility infrastructure.
